A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use
agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T =  minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

Determine the length of the hypotenuse of a right triangle if the legs have lengths 12 inches and 16 inches?
tiny-mole [99]

Answer:

c = 20 inches

Step-by-step explanation:

To find the sides of a right triangle, you use the Pythagorean Theorem.

a² + b² = c²

You know a and b, and you need to find c, the hypotenuse.

Plug in a and b.

(12)² + (16)² = c²

Simplify by solving the exponents.

144 + 256 = c²

Combine the constants.

400 = c²

Take the square root of both sides.

√400 = √c²

Solve the √

±20 = c

The length cannot be negative, so you can eliminate that as an option.

So, c = 20
